Default Which 18m FES sailplane to buy?

I'm considering the purchase of an 18m FES equipped sailplane, and would like to hear thoughts and opinions about the various options available. I'm seeking a cross country machine with long legs and a highly reliable sustainer. An 18m FES sailplane should fit that requirement nicely.

I'm a somewhat green pilot, but in the year or so before a new glider could be manufactured and delivered, I will have accumulated some more experience in my club's DG-505 and DG-1000. I have eliminated the Ventus 2cx as a possibility, due to the aircraft's reputation as being unsuitable for low-time pilots. In the 18m class, that leaves the following gliders that are available with a FES system:

- Discus 2c
- Lak-17B
- HpH 304S Shark

All three appear to have similar performance, as best I can tell from published data. I don't plan to be racing any time soon, so a difference of a few points in best glide ratio is not significant to me.

According to the flight reports that I've read, all three feature docile handling that should not be a problem for a low-time pilot. The Lak-17B and HpH Shark have flaps. I have thoroughly researched the apparently controversial issue of whether flapped ships are suitable for low-time pilots, and am convinced that they are more of an asset than a liability.

In the interests of staying on topic, let's not make this thread about flaps or the FES. These topics have already been thoroughly discussed on RAS. Please start a new thread or add to an old thread if you wish to discuss further.

I'll list some of the pros and cons of each ship that I can see, but would love to hear if anyone disagrees with them, or has anything to add.

Discus 2c
- Pros: Reputation for excellent handling. Optional GRS. Possibly higher resale value and ease of selling due to its popularity.
- Cons: No flaps.

Lak-17B
- Pros: Lower cost (better value) than the other two. Half the lead time of the other two (6 vs 12 mo).
- Cons: No safety cockpit.

HpH Shark
- Pros: Good looking (purely my opinion).
- Cons: Every flight review I've read says it handles well but... every reviewer had at least one negative thing to say about the handling. Hard to draw conclusions, but some doubt as been cast in my mind.

By now it may be clear which one I'm leaning toward. However, I wouldn't have posted this if my mind wasn't open to others' opinions, so I welcome and appreciate your thoughts. In the end, the decision will come down to what's most important to me: safety and handling. I guess what I'm really seeking is a double-check on my thinking regarding this rather significant purchase.

Cheers,
Ben


What about Ventus?
