Is string pattern just a matter of drilling holes or is there more to it before that? Why I ask is that why aren't they making exactly the same rackets in two flavors: 18x20 and 16x19 as an example. I go through each manufacturers list of rackets and it drives me nuts. It is almost like they don't want to give us what we want. Go look at Dunlops 4d line 200 - lighter, 18/20 200 Tour - heavier, 16x19 300 - lighter, 16x19 300 Tour, heavier, 18x20 What kind of logic is that? And they seem to keep that same sort of schizophrenic logic in the new generations with the classics, M's and F's. Head plays similar games, they give you a 16x19 Speed but decide to make it longer, stupid. Then we have a Prestige Pro at 16x19 but the rest at 18x20 and different weights. Make 2-3 rackets, Lite (optional), Regular, Pro and offer 18x20 or 16x19 configurations in each. Would it really be that much more overhead?
