Last I looked at this issue a lot of higher level players and top level pros used blades that were somewhere between 88-92 grams, some like even heavier like up to 95 grams.
The thing about this issue is that, because you are dealing with wood, heavier versions of the same volume of wood almost always feel more solid and give you better ball feel. So, theoretically, the heavier a blade the better it will feel compared to blades of the same make. The limiting factor on that information is that, after a certain amount of weight, the weight will start slowing your swing and your reset speeds. The heavier blade will still feel better but there are diminishing returns at a certain point where the weight has slowed the swing more than is acceptable to the kind of strokes done in TT.
This also means, someone who is stronger, more physically fit, can wield a heavier weapon than someone who is not in as good physical condition or who is smaller.
But the operative directive being, the heavier blade you can wield without losing bat speed on your stroke, the better off you are in terms of feel and power from your blade.
So, for someone like Der_Ecthe who has enough mass on him to break a fork lift and bowl over a building in a single hip check, he likes his blades somewhere around 120 grams. But for mere mortals, 85-90 grams is reasonable and if you are in better physical condition there is likely no good reason you couldn't use a blade that weighed between 90-95 grams.
I don't know that any adult I know needs a blade lighter than 85 grams unless they have an injury like Tennis Elbow and then all bets are off.
I think we better watch out about this thread though. This topic could cause Der_Ecthe to blow a few gaskets and rant like a mad-man about subjects like beast mods and the goon squad.
Say, is that Yang Ha-Eun over there? Gotta Go!
