2Pain: My first cycles were ALL 6 weeks… whether that was test cyp (7 weeks actually ;p), dianabol or deca… i gained very well from them all…
I have also known many guys IRL who gained very well from 250 test and 200 deca for 8+ weeks… newbies obviously(first 1-3 cycles).
Before the massive use of the net where we now have access to the great info we do, it was common for guys to shoot an amp of each once a week… and while there are better ways and more effective ways that are now commonplace… it can work very well if it is done.
If you are saying that some of your suggestions could make this cycle better - then i 100%, totally and wholeheartedly agree with you… however, for anyone to state that this cycle will not work is just rubbish… especially when many of you have never used dosages so low as you have always simply been told and believe that 250mg/wk of test doesnt cause any gains… it bloody does!! 
As for the stasis - i do happen to know that 8 weeks IS enough time to get appreciable gains on both deca and Enanth (as i have done it - with good diet and training 20lbs is POSSIBLE) but with the inclusion of deca i think that IF the test was run for 10 weeks, and also the Deca, and then a simple nolva PCT i wouldnt be surprised if recovery became elusive, again - in some cases.
So knowing that 8 weeks is just about enough for each, then i used the extra test to stasis and give the time between PCT and deca completion that we know as helpful for recovery.
I also think that with this cycle the gains that come will be easier to maintain too… BUT it is JMO… the OP is free to do as he chooses 
Cortes: I dont think that you would want to use a massive dose of test to counter any sides from the letro - as these sides are from a direct lowering of estrogen, as is necessary to reduce the gyno if possible. Using massive doses of test would only serve increase estrogen which would in turn reduce the low estrogen sides but also ruin the efforts at reducing the gyno…
Jman: As far as i am aware, if you are wanting to reduce Gynocomastia with letrozole use, then you need to put up with the sides, this can/will include but is not limited to: Impotence, loss of motivation, joint pains, reduced immune function. Not sure if you need to taper into the 2.5mg dose, IIRC it is Bill Roberts who is the guy to speak to with this… hopefully he will chime in and rubbish everything i said! lol 
Also IF you really have gotten another 7g of test then that changes EVERYTHING. I suggest you create a cycle based on the advice you take from the posters above, and present it to us for critique.
