I'm planning on using one for my L2 (which will hopefully happen soon, getting a launch date around here can sometimes be challenging). I've been flying fairly short/beefy rockets and some of them would benefit from being able to run the occasional baby J (one of them in particular is kind of a pig frankly) so there's no real reason not to go through the L2 attempt process with motor eject + chute release since that's what I've been happy with for this class of rocket.
I have plans to do the more traditional 3" fiberglass as tall as I am dual deploy super redundant blah blah blah rocket, in fact I have one on order, but it's going to be a little while before I build it and I want to take my time testing it - I'll probably run it single deploy with both altimeter and motor charges on a L1 class motor to start, as an example, and there's no real timetable on when I'd actually be running it as a full dual deploy, or on a J, or any of that. I don't see any reason not to just kind of ease into it.
