Protrack Gear reduction kits from Greece

Hi all,
I am thinking of purchasing a gear reduction kit from Protrack in Greece.
Has anyone fitted these gears? If so what are your thoughts on quality and do they whine during general road use?
Any views on quality v Trail Gear Reduction kits?
I am thinking of obtaining the 7%/77% kit for use with 235/75 r15 tyres, would this be better than the 17%/87% for high range road use?
Thanks in advance

There have been a number of Protrack gears kits fitted to Australian Jimny's.
Most are happy, one or two have had issues and gone with hiwow.
They are happy with the hiwow.
It's a small sample size so not definitive.

The Jimny's I've listened to with the TC gears from protrack are noisy.

I don't think the hiwow are much different.

I have the 17/87 set fitted on my gen 4 auto with 235 tyres. I find the higher revs are very useful for towing. with the 17% reduction in high, the revs at 100kph are 3400rpm and at 120kph 4100rpm. In low range, I can crawl slower than a Jeep Rubicon. The gears are exceptionally noisy in low range.

Funny as my 17/87 gears is not that loud in low. Of course there is more noise as the gears spin faster and the torque is 2-3 times or so higher. 
I was used to my old homemade 4.16:1 transfer case in my SJ. And my Jimny has been stuffed with sound deadening isolation.
Edit: Just saw the topic, sorry, mine are trail gear.

Hi Yakuza,

Is your whine noise louder in low range than high range? I will mainly be using high range so at speeds under 60 mph is the noice really noticable?
What was it like before your additional soundproofing was fitted assuming you had the low gears fitted before the sound proofing was added?

Whay sound proofing kit did you use? Was it an off the shelf kit or home made?
Thanks in advance.
