Thank you everyone for your responses. After sleeping on it... I am going to explore other options to help fund it with keeping the 1-4 as a last resort. The speed of the 1-4 is my real concern since I find myself getting up earlier and staying out later for wildlife, etc. I hope to get more into sports and I hear these two reasons alone are sellers for the 300. I would definitely go to the 2.8, the slower 300 wouldn't offer enough to give up the 1-4. You are all right, there are those occasional times I wander out and would miss the range of the 1-4... But, the AF, sharpness, and 2.8 would also be worth it going forward... hmm... Can I sell my wife's possessions to help fund lenses? Just kidding, I am not that stupid!! LOL Hell she is contributing to the purchase already for my first father's day gift, baby arrived 2 weeks before it, can't say I am a worthy dad yet!!
