I'll try it but I don't think it'll be easy, in this run I got to the check in 35.2x sec, it's my best second check ever, then I died but I wasn't trying to beat the record, so I used the check, when I took control of sonic again I did a homing attack then charged a spindash and started the decent, I hitted the springs at low 41, but the main cause that made this run be so fast was my ending, my scream was because of this more than anything else xD, my ending was too fast, since I simply can't do the ending right with blasest's strat, I tried with my old one, from my 51:47 run, but this time I did it perfectly.
I don't know when I'll get a camera again but be sure I'll at least beat your time in video, 'cause after this run I tried again and got 50:40.
One more thing, I've discovered 2 new little shortcuts on Green Forest: the first one is use the gravity control in the first loop skip instead of just do a homing attack, and the second one is in the beginning of the part where you go up the tree, when you hit the first spring, try to get the light dash in the middle of the way, stay holding the "B" button down and charge a spindash, now for the hard part, with the spindash charged aim to the wall in front of you and do a superbounce then immediately when you see the spring do a homing attack on it,if you done it fast and right you'll save at least half of a second.
Obviously it's hard to do in a great run, where you'll probaly be nervous at this point of the stage, but with this I got 1:30:99 in GC, could be lower if I don't screwed up my ending and used the third and the last checks :P
See ya'll dudes ;)
