Just re-read my original post. I was talking about an Electra 150, not the SIL. My mistake, poorly worded :-)
I have jumped a 150 SIL and was happy with it, but the Electra 150 has a MAX exit weight of 70KG. I know this is out of my weight limits (most people over 6ft too) it was more of me just enquiring as to why an intermediate eliptical canopy has a MAW of 70kg, just seems significantly lower than any other canopy,
