This past Christmas I got G3 and fly on it about every other day. Now I can take off, fly, and land the trainer and my newer Spectra Select sailplane with little or no problems. Getting a little boring, actually.
My next project is a Model Tech Magic Extra 300 which is almost ready to go. I know it's a big jump but with low throws and some expo I think I can handle it. If it makes it past the trim flight I'll get used to it with ovals and figure 8s for a few flights, then progress to mild aerobatics I've been practicing on G3.
I fear you're making a bit too big of a jump to go from a trainer to the MT Extra. The airfoil on the Extra is thin which means it doesn't develop much lift. It's also not the lightest .25 size plane. These things mean it requires significantly faster landings than a trainer and won't be forgiving if you stall it. Low throws and expo are not going to protect you from these issues. You would really be better off flying a more forgiving low wing plane between the trainer and the Extra.
