If you are going with a single pin I would put it on the MR6 vice the Heli'm due to the fact it is faster. That bow is a killer in the right hands. Good luck
Well I had a little downtime at work and looked at ebay. Found a HHA OL5519 with the 2" housing listed as a buy it now for a really good price so I got that too. Good thing I get paid friday...
