Need advice on trade

[slw87]

I am in an 11 team mixed league. The scoring system is as follows: AB -.25, R 1, H 2.25, 2B 1, 3B 2, HR 3, RBI 1, SB 1, CS -1, BB 2, IP 6, W 6, SV 6, H -2, ER -1.25, HR -3, BB -2, K .5. I have been offfered a trade that is very intriguing and am wondering whether I should take it or not. I would be giving up Derek Lowe, Russel Martin and Koske Fukodome. I would be recieving Geovony Soto, Johnathan Papelbon, and Kyle Lohse. also if you look at it the relievers are of higher value also because there is a max on innings so their pts./ip rate is higher. Should I pull the trigger?
