If you want two for only 5-6 months and for bacon you wont want a tamworth as they take longer than that to get to bacon weight (around 90kg + liveweight).
We have a welsh pig (WE) and a oxford, sandy and black (OSB) who are both 23 weeks old (bought at 10 weeks old) and weigh in the region of 90kg for the WE and 70kg for the OSB, they are off on June 10th. they have been fed 18% protein diet (farmgate growers) and for these last few weeks will be fed on a mix of growers, crushed oats and flaked peas. They were on a ad-lib diet till 20 weeks, and then restricted as the OSB was starting to put a little to much fat on.
We aim to get the WE near 105kg liveweight by slaughter.
The WE roots well, but doest dig too many hollows and he likes eating the things he has found whilst digging, the OSB digs less and generally gets bored with it, but will maintain the wallow and dig hollows for laying in. They are outdoors in a 5m x 15m pen.
Other good pigs for bacon would be large blacks though to do bacon well from them they would need to be around 8 old before they went off, they are very docile as they have lopped ears (like the WE and OSB).
Large whites can also be used for bacon, and really any traditional breed crossed with a modern will be quicker to weight (if you like the idea of crosses, as some people dont).
British saddlebacks are a bacon pig, but they can put the fat down, but if you find a cross of them with say a (large white/hampshire/duroc/welsh/landrace/pietrain) then they will take a little longer till they start laying the fat down.
I dont really have an opinion one way or the other to pigs as i've worked with most breeds, though i will add that tamworths do talk the most and the saddlebacks i've worked with are rather boring, however they all have their own personalities.
My personal favs are WE, large black and durocs (all very different).
