| 452X and 8125 are both excellent materials but you need to decide/find out which is best for you not someone else, the best way to do this if you can not lend a string is buy sample spools ( clickers have a really good selection at very competative prices). A sample spool should make a min of 4 strings dependant on number of strands used.
For serving I won't use anything other than Halo anymore but equally I have not tried the Angel serving and I know a lot rate that very highly both seem to be very smooth serving.
Personally I have found 452X a bit quicker but a bit less forgiving than 8125, so between these two you need to decide which you prefer a bit more speed or a string that is a little bit more forgiving.
I won't use anything other than dental floss anymore either, Brass is too heavy and just do not fancy the Beiter nock but that is personal choice.
Lastly I serve about 1cm above my tab and about 3 cm below again this reduces string weight.
