rem700LA Stock???

[PFCSkoug]

Ive been looking around at new stocks for my 700 I really like the look of the MCM A-4 but people seem to really prefer the A-5 so whats the difference between the two. Ive also been told to look at the Manners TA-4 (i believe) but havnt really heard much about them or i was evan maybe thinking of a AI chasis. i know ive narrowed things down so much but if you could give me your opions on what might be a good LR hunting stock.
Thanks
