well over time and many tests - 3D is wood and imac is CF - now on the DA50 i always get back to 22 x 8 bolly wood as it gives me good allround performance. lots of guys use 23 x 8 but i find response sluggish and for 3D you need spool up and good rpm. whats was interesting is that on my Chip double vision i once use a zinger 22 x 8 and was surprized at the performance as i could throw the plane around with ample power to spare - interesting?? but out of principle i have not done it again - LOL
