If you have something that is an actual improvement, bring it on. If its another dual face, bladder filled with gas, specialty grooves, you the nominal bull shit that you have to hype because you know it impacts the real outcome by less than 2%, don't waste the time/$ to produce it. IMO, if you are building components in this day in age, what you bring out had better be GREAT, not really really good, let alone just good, there is a market filled with that already and people do it cheap. If you aren't feeling ready to prove you can take out TM, Callaway, Cobra, etc, don't bother. If you can't PROVE your stuff is better, don't bother. I'm not coming out to buy your new $200 head and have to go find another $150 shaft to put it all together with to try to see if it works. That's not the market now. There are a ton of adapters that allow for super fast shaft swaps, at demo days where you can dial in the combo you like and go. Best part, you can even tweak it once you buy it without specialty equipment. So you have that to overcome, do it big or don't do it.
