I always come back to my Cobra L4V 10.5 with stock rayon R flex shaft. I have a golfworks defiant/nvs, TM burner speed something???, and CT250D/ys7, sasquatch/dvs, and I enjoy hitting each one, except the TM. But the L4V is my straightest, longest, easiest to hit driver. It makes me wonder if I should try out a cobra F6. I've never used an adjustable driver before...mainly because the adjustments would probably drive me crazy. Every time I hit a ball off course I'll be adjusting something. Here's a shot in the dark. Has anybody hit both the L4V and F6?
