That all depends on what you are looking for and what you consider "better". Generally though, if a supplier changes specific varieties in a blend, the new ones they pick will be very similar to the previous. I was pretty big on prg a while ago and purchased a 3-way blend from MVS. The varieties changed over time (Apple GL > Apple SGL, Stellar GL > Stellar 3GL, etc) but they all performed the same. Same with the 5-iron blend from United Seeds.

The SR4000 I believe is the older varieties which came out in the early 2000s. The varieties in the other blend have been around since atleast 2010. Nothing is from 2025

 

Hancocks listing is inaccurate. It said the same thing in June when I ordered a bag from them and the blend I ended up receiving was 44.28% SR 4700, 34.86% Banfield, 19.7% Tetrasport. Probably the only guaranteed way to know what’s in there would be to contact them and ask for the label.
