RE: what do i need to do
Although the Muzzy is a fine rest,it is overkill for your setup.You can get a quality rest for much less.I like the idea of getting rid of the WB but I wouldn't reccomend spending that much for a rest,AT THIS POINT.NAP Quicktune and the Trophy Taker are both only 50.00.Tru Glo makes some fine sights but just make sure it is one of the higher quality ones and has a level.Aluminum,not plastic.Bright Sight xtreme looks like a decent one.
You will need to contact Gibblet about the price of his strings,I have no clue.
Scott Little Goose is an excellent release but I would reccomend the Tru Ball Short & Sweet II over it.I have had both.
