I have a SIMS modular stabilizer. I like it, don't know if it was worth the extra $$$$. I wish it was a bit longer to add a bit of forward weight. I could add another modual, but not for another $30 (or whatever the signle unit is). I was going to add an s-coil to the end of the mod stabilizer, but the guy at Cabelas said it wouldn't be worth it.
