Yes - certainly think long term. You are going to have significant equipment on site and as such they can do some work and save you some money later (moving that equipment isn't cheap).
A perimeter trail is ideal, but not always possible. I would love to have one on my place, but it just isn't in the cards. Plot locations and even just openings created are great as well. Also consider any sort of culverts or the like to improve access.
You can also have them position the tree tops into rows and the like if you want to manipulate movement to some extent or to create screens. Or put them in clusters for deer to bed near. But location of these things is important - again...plan.
The more detail you go into and document the fewer "surprises" you will have.
I was VERY involved in mine....I live on the property and I approved the removal of each and every tree (700+) as we took the inventory and marked them all. I also had them remove some they didn't want (too big for me to screw with). I followed up every day on the progress and the like.
If you have never had this work done before - be prepared to have the "What the hell have I done" moment complete with a big knot develop in your stomach. I went thru this. I was almost reduced to tears as I thought I had destroyed my woods. Well, it turns out my misery was ill founded and short lived. Mother nature bounced back and I look forward to the next cut.
Goodluck.....OH and take lots of BEFORE pictures...so you can take AFTER pictures....at some point you will be glad you did.
