VS006

Yet again.....Help:)
I am intending a trip to Florida at the end of April. Outbound LGW - MCO (VS15)and inbound MIA - LHR (VS006).
However, my dilemma is that the data on this forum shows a 346 from MIA, with a 343 as a 5% chance. Using the availability tool, all dates around 14th May are showing 343; thus no chance of suites.
Which is the more likely to be correct?
The availability of Z is getting lower and I therefore need to book soon. I need to make the decision to abandon Revivals and come back MCO - LGW to get suites or have a high likelihood of 346 suites into LHR
[BTW, I am assuming that the 346 refits will be completed by May and therefore any 346 into LHR is likely to be UCS]
