Fritz,
Ahh, now I think I understand. I thought you actually wanted to put one of the small Sims modular units in between the extension bar and the "donut" part of the Enhancer 2000. What you actually want to do is put the Enhancer 2000 and a modular unit on the back of the bow itself.
My misunderstanding.
As for where I live...

...right up the street from you in New Tripoli. Would you like me to drop the "Short" Enhancer 2000 off tonight or tomorrow?
I shoot down at Bait and Bow in Allentown but they only have a 20 yard indoor range as well. I belong to a few local clubs in the area but with these temps I am not using their outdoor ranges. Come the first Sunday in February I will be over at the Slatington archery club to shoot the first 3D of the season...you going?
