My math, assuming two pair or better on the flop holds up, but nothing below that improves (bad assumption, I know):

Also, I used the percentages calculated in http://www.flopturnriver.com/phpBB2/...ghlight=sticky

Code:
flopping EXACTLY two pair by pairing EACH of your hole cards                         2.02%
flopping EXACTLY trips by flopping two cards to one hole card                        1.347%
flopping EXACTLY a full house, trips of one hole card and pairing the other          0.092%
flopping EXACTLY four of a kind, three cards to one of your hole cards               0.01% 
flopping a straight (including the slight chance of a straight flush in some cases)  1.306% = 1.306 * 99.158 = 1.295
flopping a flush (including the slight chance of a straight flush in some cases)     0.842% = 0.842 * 98.604 = 0.83
Total: 5.594%

flopping a four flush => it holding up                                  10.944% = 9.8 => 3.3%
flopping an 8 out straight draw => it holding up                        10.449% = 9.305 => 2.81682%
flopping sf draw => it holding up	                 					    10.944 * .10449 = 1.144 => .598265
Summing all of that up says that with suited connectors you will end up with a flush/straight or FLOP two pair or better a total of 12.31% of the time. I would think that the times that flopping one pair or less develops into a killer hand would about cancel the amount of times two pair or better isn't the best hand.
