I would get 52 because with those stats you have a pretty good chance of smiting out a good item like claws or a gs. Aswell as you have all 3 of the 15% prayer which really help in bridding.
I'm in the same dilemma, considering I have 13 prayer though. I Want to get 52 prayer for smite and melee prot to be able to chin my way to 99 range. But then again, if I stayed 13 prayer, it would look really cool with 99 range and str and Mage.
44 or 52. It's only 1 combat level difference from 44 to 52 , maybe 2. Either way those are the only ones that are worth it. 43 Is completely worthless unless you have no range, but you do, so 44.
If your Attack level is 60 or lower, 44.
If you have 75/80 Attack, have access to Chaotics/Godswords, you should get 52, as you hit very high with those, and you will Smite a lot of items
Personally i'm an 80 Attack pure with 52 and I love it, but on my 60 Attack pure, I never have went past 44 because it's all you really need. It doesn't matter if you get smited for your Dragon Scimmy.
