In a word, no. In a few more words, of course not.
Assuming that the goal is lower scores, how much would your scores be affected by theoretically gaining a couple more yards on heel/toe hits? Relative to the cost of a driver, is that worth it? It's a lot of money to spend for "maybe" a couple yards on mishits that will "maybe" result in how many strokes gained per round? Almost zero?
But, new stuff is fun. It's OK to get something new for fun, and if it happens to work better - great! I think the newer Cobra stuff will even work with your existing shaft/adapter, so that could be of some benefit. You could compare head to head. Check that before you buy, though. I could be wrong.
The F7+ is awesome. Great sound, great look, monster distance for me. Most of them are great. Pick one that looks cool to you and give it a rip.
