With a longbow often a "dead on" spine or even a little less will work well for me. By dead on I mean matching the spine poundage of the arrow to the weight of the bow.
For your bows, a 2018 spines at about 67#, a 2020 a bit more than that so they could be a good fit for you. A CE Terminator in 45-60 might be worth a look also. For a woodie I'd start experimenting right in the 65-70 range.
If you look at tpoofs post right before mine, he is shooting a 60# Jerry Hill and 2016's. The 2016 spines at 61#.
If your draw length is shorter than 28" you will need to go a little lighter, and if its longer a bit heavier.
I'm guessing the spine rating of your 300's is over 90 pounds or thereabouts.
