I am familiar with the area. Made a lot of trips to Ames, DM, and other stops along the way.
If you don't already have 'em, get vol's 1 &2 of the Grendel handbooks. You can order 'em from BFT, and they have a wealth of info. In one of the vol's is a graph of barrel length vs velocity. You'll find very little diff in 18" or 20" vel's but the extra convenience of the shorter barrel ( when walking ) is note worthy. Keep us posted and do pix when appropriate.
