I have the GBB heavenwood and I'm usually in the 200-210 yard range with this club. It is pretty comparable to a 5w, in fact my distances with both are nearly identical.
The exact yardage you see with each of those clubs will vary by player because every player's swing is different. The different swings produce different launch and spin numbers with each club, so for some players they might spin the 7 wood too much and it goes shorter than the hybrid and on others it will be the opposite.
I encourage you to try to test both and see which one gets you the yardage that you want to see.
@MasonWc698 -- It sounds like a 5H would be the way to go. Don't worry so much that you would have two "5s" in your bag. Its all about gapping and especially if you hit the 4H that well, I would imagine a 5H would work great too.
I bought the Epic heaven wood to replace my 4 iron (180-185 yards). But found it to long for that. I have been hitting it 200+ yards off the deck. Hitting it 180yds out of the rough. It is an incredible club. Needless to say I had to put my 4 iron back in the bag. Thinking very seriously of getting the divine 9 to replace my 4 iron now.
@JimEis1 why not go with a 4H instead? My 4H is my 180 yard club. I also hit my Epic HW 200 yards. Sounds like we probably have the same distances on our clubs. Unless you hate hybrids I'd suggest you ditch the 4 iron and go with a 4H instead.
PC98...thanks for the imput. But yes, I do not do well with hybrids. They had a club demo day at my golf course Saturday. I tried the divine 9 and fell in love with my next club. Hitting the right distance plus much higher than a 4 iron or a hybrid. Ordered it with a Fujikura Pro 72 shaft, just like I have on my heavenwood. Only thing I would have liked to have changed on it was having the capability of an optifit hosel.
