Dave,

Robart has made the mini air retracts available,and the price looks good as well.
Still have yet to get my 602`s from spring air but maybe tomorrow, i will get the weight and post them soon as i get them in hand.
Going to try those robarts on my ursa major 25, so i will be able to see if there is a weight difference.

And your build is looking great!!!!
