Front focal plane is nice if you are using the recticle to range things. Most american scopes are second focal place, so when you turn the power up the recticel gets larger as well. So a SFP scope has a specific power that it needs to be set at for the reticel to be accurate. (talking Mil-dot). A first Focal plane can be used at any power. The rectile stays the same size as you turn the power up..It looks like it gets smaller and larger but the distance between the mil-dots stays the same. Most of your tacticle guys like FFP.
The ER/T is a nice setup, I just do not think the avarge shooter needs FFP scopes. ANd the use of modern range finders, the ranging aspect is not needed.
I hope i have not confused you and if i did let me know and i will try to explain it differently.
I would look at the VX-III 6-20-50 with side focus,fine duplex and standard knobs Then I would have the custom shop install M1 knobs on it. If you need more power then go with the 8-25 but the 20 power will get you to 1000 no problem.
this is a personal choice in reguards to the rectile. I like to dial for every shot and hold dead center. If you like to hold off then the Mil dot or TMR for leupld is nice but not as good as the Nighforce NPR selections IMHO.
Hope this helps..
