I think the cruise is a great suggestion.
I also think that the tren v.s. oral in regards to safety, is relative.
Tren will screw over cholesterol levels mang...as far as i know.
I do however agree that you need to cycle a highly anabolic compound in there:
And tren is the drug that comes to mind.
I think you should run it 10 weeks on...and 16 weeks off (the extended off time being introduced to allow you some time to attempt an aggressive cholesterol-management protocol.)
You plan on being on for a year so i'd like you to look into two sets of cholesterol-lowering approaches.
The first would be homeopathic: Niacin

The second would be pharmaceutically aggressive: Lipitor (atorvastatin) (or any other similar compound: Norvir; Fortovase; Pravachol; Zocor; Baycol ; Lescol)
This would be used, in addition to Niacin, in the 16-week period that you're off Tren. There are risks while using both (e.g. high doses of Niacin can cause an elevation of liver enzymes etc.)...but there's a risk in what you're doing also... Good luck man.
Sidenote: If you take a cholesterol-lowering drugs you need to supplement with co-enzyme Q-10... as these drugs deplete it.
