It occurs to me I could coach you on singles tactics ... but you could coach me on hybrids. You have been a busy guy since Jan. So you tell me the difference you expect between full bed Cream vs Cream/Sheep.
We all have different needs. One of my primary needs is to support my JR player with proper equipment.
I started down the poly/sgut road as a result of putting a rev limiter on strings. Specifically poly strings. I do believe a full bed of poly will yield performance benefits beyond a hybrid for the right player. I think for my son, he could possibly hit better with full bed of poly. But that would also entail vigilant monitoring of duration and tension of his strings. And I think it can be done. But...
With a hybrid, I know that the performance of the string combo will most likely fall before the dangers of hitting with dead poly surfaces. So if we don't re-string in time, it's ok. Performance suffers, but arms shouldn't. Cream is comfortable. But Cream is still a poly and subject to the dark side of poly.
A secondary benefit (and a really good one at that) is that by crossing any poly with an inexpensive sgut, I am able to experiment with different strings for essentially half the price. Let's take the example of Cream:
If I were to use full bed, then I have committed a full set to a single tension. Depending on my impression, I may want to string again at a higher/lower tension to confirm. It will cost me two sets of Cream to confirm whether I like it, or I only like it at XX tension. If I like, then order more.
With a hybrid, I can get two stringings and thus two tries at the correct tension to rule yay or nay. If it is a yay, I can keep playing with the acceptable hybrid performance or I can venture into getting the full impact with a full bed.
Again, my primary goal is the right equipment for my junior player. My needs come second.
Having said that, I don't think I'd be using Cream for my son. He's onto Cyclone and HyperG hybrid. Restring every other week. It's possible he can get double the life if he went full bed and most likely get a bit more performance with negligible comfort issues. Again, IF we are vigilant in cutting his strings on time.
But the third benefit is by having the sgut help tone down some of the performance, it helps him stay focused on good technique and not relying on his spin monster strings to bail him out. Maybe halfway through his HS tennis, we can take the rev limiter off and let him go for whatever top performance is available...
Now. If I didn't have a Junior player in the house. I'd be less inclined to hold the line on hybrids.
My guess is that having a slick cross with durable surface would provide a bit more spin, comfort in a different manner and possibly more durability for the average player. I still wonder about the playability if you don't use a lot of spin? Now you have two strings with 170 stiffness instead of one at 170 and one at 145.
So now that I've made a short story long, I think while I am experimenting and gathering data, I may hold the line on hybrid setup. Then once I've got to a point where I really, really like a string, I'd like to try full bed at least once. Then I can decide if I keep going full bed factoring performance, cost, durability, comfort.
One gotcha that I need to express is that some strings may not work well in hybrid form. I found my results with Cyclone Tour to be bad while I've heard some others find it to be fantastic. It may be that there is quite a difference in performance from full bed to hybrid.
