Alright, got the reel 3 days after I ordered it ( scuba store never ceases to amaze me) and it is in place on my RA 90. My ra 90 is my shoredive gun, will be using it for halibut and calicos. I used the 1.5 mm cressi sub line(got 50 m of that at scuba store also for 14 bucks or so), and the reel took all that with room to spare. Will see how the 1.5 mm line performs. My other reel is set up with 2.5 or so tuna cord, basically Im used to thicker line. Dont know the breaking sterngth on the 1.5 stuff, but it feels pretty strong.
Im no engineer, but it looks like the reel is designed for guns WITHOUT a rail. If you have a barrel free of obsruction, you can use clamps that come with reel to mount to round gun barrel. If not, you have to do like I did, take a deep breath and get out the drill and screws, and screw to bottom of gun. RA's own reel requires a similar procedure, so I gues its not really that big of a deal. The reel sets reel well on an RA barrel, feels snug. Reel is made of some kind of fancy plastic, but it feels pretty supple. My glock is also made out of fancy plastic, and that works fine as well. The drag seems prety good. I always leave my drags set really light, so that should be fine. Havent gotten it wet yet, but the whole setup looks pretty good to me. Basically, the whole package got droped of at my front door for just over 50 bucks, reel and line. Pretty hard to get a good reel stateside for that price. I would recomend it.
