Recommend filters for a 95mm lens

Ok I'm using a irix 15mm lens. I've been really happy with it as a budget prime wide angle lens. Problem is I don't have any filters for it. I've like playing with ND filters in the past. They get pretty expensive for a 95mm lens and I get that u get what u pay for. My question is are the cokin x pro 130mm filters any good. Says they are resin but then states it is organic cr-39 glass. I assume for the price they are resin. For a 3 piece set and adapter for $200. I have a smaller set of cokin nuances filters that I use on my 77mm canon lens. They are glass and do really well. But for this larger objective lens they nuances line runs $350-400. I have a budget and can't afford that right now. Curious if anyone has experience with their cheaper resin filters and are they worth buying. Also any other brand or filter options recommendations welcome.
Thanks

My experience with COKINs...Way back in the late 1980's I purchased a number of COKIN filters for use with my medium format kit. Due to the bulk of carrying many COKINs, I purchased a vinyl filter wallet to hold filters, rather than the individual COKIN boxes they were sold in. I took them on a photographic holiday to SW Florida, driving from location to location and getting out for day hikes when in places of interest. After several days, I found an opportunity to use one of the COKIN filters. I pulled out the filter wallet, pulled a filter from its slot, and discovered that dust had accumulted in the wallet and had abraided all of the resin filters, ruining them! I threw them all away, and never replaced any of them.
So you really do need to use the bulky COKIN box, unless you are willling to suffer a similar fate to mine. And wash dust off under running water, so that you do not abrade them when wiping off dust with a dry cloth! And, do not bother getting COKIN neutral density filters, which are acknowledged to put a noticeable tint into photos because their ND are not truly 'neutral'.

There's nothing Neutral in the Cokin plastic "ND" filters. "CR-39" and "optical resin" is marketing speak for plastic. You'll loose sharpness, contrast, and gain a random color cast. Some are purple while others are bluish. That goes for all their plastic lines, no matter if it's A, P, Z, or X series. The only thing crappier is Tiffen filters.

With that said, the Nuances Extreme line of glass filters are actually pretty good. BUT, be sure it's the glass ones, the Extremes. There are some of the Nuances that are not.

Lee is the same - their older "resin" filters are junk, no matter how good people say they are. The Lee 10-stop is an overpriced joke, unless you like massive color tints to your long exposures. Yes, the price for quality glass filters like the new glass Lee, Formatt-Hitech, and even the Nisi are high, but worth it in the long run. If you truly need ND Grads to create your image, pay the piper and get good glass so that when you pull them out, you know they'll do the job and not waste your time. Beware that there's also a lot of overpriced mediocre crap out there too, optimized for those who like the look of their gear instead of their images.

I use a 150mm system with 95mm filter ring on my Hasselblad glass. I tried the X-pro once and the loss of resolution was immediately noticable, especially at 100mp. Stick with the glass filters - and get rectangular ones so that you can adjust them as well as using them on other lenses.
