I have been thinking about doing the samething. Me personally I love this set and no thoughts whatsoever about changing to another set, but have been thingking about the speed parity up in the 80-90 range after reading on Flazkos sets. I'm willing to test some with you if you want to see what will happen. Again for me this set is almost perfect.......well for me it is perfect, but making things a little more challaging is never a bad thing!
