Again, there is no getting fielded to death on this hand - there is only the other table, and they are playing 2/1. 1NT 10-12 may be terrific nonvulnerable at matchpoints; I lack the experience to know, because we play this system only at IMPs.
The two main advantages to the 10-12 NT:
1. NV, you win the board hands-down at matchpoints if you are allowed to play there (easy to see why - 6 tricks = -50 if we play 1NT, -90 if they play it. 5 tricks is -100 if we play it, -120 if they play it. And if we make the 1NT, turn the previous scores around and make them positive)
2. Pre-empting the opponents, who have no idea whose hand it is, while pard knows all (best coupled with major 2-bids to play, as you seem to have)
3. Continuation of number 2, the opps are always desperate to get into the auction when you open a 10-12 and they seem to end up in the wrong spot more often than not
Number 1 only applies at matchpoints NV, but number 2 applies in any situation. However, at IMPs, there is the extra risk of going for a number on a nothing board (on rare occasions you may find yourselves forced into the auction when you didn't want to be with two mediocre balanced hands). So if you only do it non-vul, you retain full advantage with none of the risk. IMHO you are totally missing out not playing this at matchpoints - it is quite effective!
BTW I have a decent system over 10-12 NT (probably has similarities with the one you already have) and a very effective escape mechanism when doubled, PM me if you want to know them :-)
