I tried obliques only ( Memo + solve ) it took around 25 mins , so obviously 6BLD will go over an hour , at first I tried U2 , but it was hard to turn the right layer , so I switched to r2 and it worked fine with meUpdate: as with most thing cubing, practice did the job.
I can now say that I 'see' the obliques
I will stick to solving obliques (and some center-centers) from written memo for while to improve accurace. Only then I will invest the time in memoing for full solves.
With my 5BLD times in the 35 min range and the extra care needed for taking the correct slices in 6BLD I expect going over the hour...
