I am actually tempted to do the same. The weight saving with the additional reach and performance with the TCs is very tempting and I can wait a few more months to save some more.
Oh I'll need more than a few more months but for me I get great results with my 300mm + 1.4x and 2x. The biggest improvement for me would be saving for the 600mm so I will just do that. If I change my mind by the time I save the money I could make a nice down payment on a car! LOL

Just wait until the sample pics hit the forum!
