the only thing with the review for the nela trowel is no one is goin to be able to comment on how the trowel wears in and the last ability of it, that will take time and we dont have time so its all goin to be based upon speculation of the initial useage, but the s*p*r*lex ,IFF its anything like the refina you will be able to get out the box and finish with it straight away you can judge a s*p*r*lex easier than you can a straight trowel simply because the s*p*r*lex is mustard out of the box and you are expectig a certin amount of play in the blade, so with these new superflexes you will be able to just hold the trowel bend the blade in your hand and you will instantly know how much flex you are goin to get and the responsivness it should give you.
with the straight trowel you can look at the weight balance strength and comfort of the trowel and yes you can finish with them out the box but a normal trowel IMO will get better with time as it wears in, time that like i said we dont have.
the s*p*r*lex reviews i feel will be a more accurate review as they are ment to be an off the bat trowel:RpS_thumbup:
