The SM rig looks really interesting
I think there is perhaps a couple of difference btwn Maramu and Super M in this instance though
My Maramu might be typical of others of the same vintage in that it does not have the original furler with the 3 track luff with the ability to use a mouse to release the ballooner. As such, i'll never fly the ballooner and genoa on the same furler as they cant be taken up / down independently. So to me the ballooner has only been used as a cruising chute - flown solo in light airs & without the genoa - ie not very often !
Also my Maramu does not have powered cockpit sheet winches - I've been really happy with the slightly smaller cut genoa as it makes winch work easier and better sail shape upwind but again some of the SM I have seem have nice (aftermarket?) staysails which perhaps help in this department too
All the best
