Is boss rush / beacon farm worth it this last into a season ?

So I had a last season start and decided eventually to play iris2, but dont have her pets so using blue dmg pets. Im currently at 500mil dps with T2 mods and some random +1 level slates.

I can do boss rush in T7 and damage feels good enough for beacon farming in T8 as its 500mil dps but magus hit the whole screen so clear is good. However having to manually pickup T8 make it a bit more time consuming per map.

My overall goal at this stage is just to get enough currency to buy gear to get into profound and clear SS15.

So im wondering should I be boss rushing until I jump straight to profound, beacon farming in T8 or just do something totally different like black sail / sandlord and sell memeory and crafting materials ?

Im not sure how hard T8 beacon farming / T7 boss rushing falls off later on into the season.
